1 Claim.

This invention relates to a silo, and more especially to a silo composed of brick or cement blocks, with a reinforced band of concrete appearing between each layer of the blocks, and having doors or openings spaced vertically of the silo with a reinforced binding medium disposed between the layers of the blocks on each side of the door, and being secured to the door frame and extending entirely around the silo. By providing a silo constructed as hereinafter described, a very rigid structure is provided which takes care of any tendency to bulge outwardly as each layer of blocks is not only cemented together, but'a reinforced ring extends entirely around the silo between each layer of blocks to therefore prevent any tendency towards outward bulging due to the outward pressure of the contents of the silo.

It is an object of this invention to provide a silo construction in which the silo is composed of layers of blocks, with the proximate edges of the blocks having cavities therein registering with each other so as to provide a continuous cavity around the silo between the adjacent layers of blocks, and within this cavity is disposed a reinforced concrete ring to not only bind the layers of blocks together, but to serve as a brace against outward movement of the blocks composing the silo under the stress of the contents of the silo.

It is another object of this invention to provide a silo having suitable door frames therein, with the doors being anchored on each side to a reinforced concrete member extending from one side of the door frame entirely around the silo and being secured to the other side of the door frame, so that the door frame forms a link in a circular reinforcing member which extends entirely around the silo, and embedded within the blocks forming the silo.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds when taken in connection'with the accompanying drawings, in which:

Figure 1 is an elevation of a silo constructed according to my invention, and showing the top removed;

Figure 2 is a view taken along the line 2-2 in Figure l, with the upper portion of the silo removed;

Figure 3 is a vertical sectional view taken along the line 3-3 in Figure 1;

Figure 4 is a vertical sectional view taken along the line 4-4 in Figure 1;

Figure 5 is a vertical sectional view taken along 55 the line 55 in Figure 1;

Figure 6 is a front elevation of a door frame member;

Figure '7 is a cross-sectional view taken along the line 'I-J in Figure 6;

Figure 8 is an enlarged top plan view looking downward on a tier of blocks and before the cement mortar has been applied thereto, the blocks being shown in a, projected view without being curved as they would appear in the silo structure;

Figure 9 is a top plan view showing the junction point between one side of the door frame and the adjoining blocks in a projected straight line, and before the cement mortar has been applied;

Figure 10 is an end elevation of one of the cement blocks used in the construction of my silo.

Referring more specifically to the drawings, the numeral l0 indicates the footing of a silo which is usually disposed within the ground, the ground line being indicated at I I. Disposed on the footing I0 is a circular series of blocks l2. These blocks .are shown in Figure 10, and it is there evident that the upper and lower edges of each block in the silo has a semi-circular cavity I4 in its bottom edge and another similar cavity l5 in 1 its top edge.

The footing I0 is poured with a circular cavity therearound which is semicircular in cross-section and is similar in all respects to cavity l5 shown in Figure 10, and this cavity appears in Figure 5, but is filled with concrete mortar. The cavity in the top of the footing has placed therein a rod or cable l6, and this is passed entirely around the silo and its ends are overlapped as shown in Figure 8. Before this rod or cable 16 is placed in position, a suitable amount of concrete mortar is-placed in the cavity l5, then the cable or rod is placed in position with overlapping ends as shown in Figure 8. Then an additional amount of cement mortar is placed over the cavity l5 and over the rod or cable I6, there being sufiicient mortar to fill cavity l4 when the next layer of blocks is placed in position, and also to provide laterally projecting wings I1 and I8 as shown in Figures 3 and 4' to form a binding agent between the layers of blocks. After the concrete and cable have been placed in the cavity in the footing as above-described, the concrete blocks or brick l2 are placed in their position on edge, and then concrete mortar is placed in the cavity I5 in the upper edge of the row of blocks l2, and another cable or rod I6 is placed in position with overlapping ends and then concrete mortar is applied and the next layer of blocks [3 is placed in position. Then the operation is repeated as to the upper end of the blocks 1 which can be opened from the outside.

in the layer [3, and a door frame 20 is placed in position, and with door frame 20 in position, a 1ayer 2| of concrete blocks are placed in position, and these rest against opposed sides of the door frame 20. Then concrete mortar is placed in the cavity in the upper ends of these blocks 2| and a cable or rod 22 is laid into the cavity, and its ends are passed through eye bolts 23 and 24, and the ends IQ of this cable or rod are doubled back on the rod or cable as shown in Figure 9, and then an additional amount of concrete mortar is placed over this cable or rod and this locks the ends together when the next.

row of bricks or blocks 26 is placed in position. The door frame 20 is provided with cavities in its upper and lower edges identical to the cavi- I ties l4 and I shown in Figure 10, with the layer 26 in position, a cable or rod ls'led around the entire periphery of the silo, and its ends overlap as shown in Figure 8, after concrete mortar has first been placed in the cavity IS in the upper edges of the door frame and the concrete blocks. forming tier 26. Then an additional amount of concrete mortar is placed in position and the next tier of blocks 21 is placed in position. The remainder of the silo is built in recurring series of concrete blocks or brick and door frames, as thus far described, as the remaining door frames are identical to the ones described and the tiers of concrete blocks or bricks are as described and in the same recurring series as thus far described.

Each of the door frames has bolts 35 and 36 on one side and 31 and 38 on the other side, and these project outwardly and are adapted to penetrate holes in upright portions 40 and 4| of a ladder mechanism, said ladder mechanism having a plurality of cross rungs 42 so that the silo can be scaled from the exterior. Each door frame'has an opening which is filled by a suitable door such as 45. This door can be removed only from the inside of the silo, and of course, the top portion, not shown, has a conventional door It is quite evident that when the silo is being filled in the fall of the year with silage, that all doors are removed and then silage is first introduced through the lower door, and when the silage rises to the lower door, this is closed from the inside,

i and silage can be introduced through the next door above, and this is continued until the silo is completely filled at which time the door at the top provides an exit for the person which may be within the silo, and this door is firmly secured from the outside. The door in the top and the top structure is not shown, as it is of conventional design and structure. I

7 After the silo has been completed, a layer of waterproof cement 46 is placed over the entire inner surface, excepting that portion of the door frames which is occupied by the doors 45.

In the drawings and specification, there has been set forth a preferred embodiment of the invention and although specific terms 'are employed, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being defined in the claim.

I claim:

A concrete silo comprising a plurality of superposed layers of concrete blocks disposed in a circle and forming the wall of the silo, the upper and lower edges of each block having an arcuate groove therein registering with the grooves of adjacent blocks and a reinforced concrete ring extending entirely around the silo between some of the layers of blocks, some of the rounds of blocks having a door frame disposed therein extending vertically for a plurality of layers of blocks, said door frame having eye-bolts extending from each side thereof and fitting between two rounds of blocks, and a flexible metallic member disposed in the space formed by the arcuate grooves in the blocks forming the two rounds between which the eye-bolts fit, the ends of the flexible metallic member being passed through the eye-bolts and doubled back into the space formed by the grooves in the two adjacent rounds of blocks, and a layer of mortar binding the rows of blocks together and filling the space formed by the grooves in the adjacent rows of blocks and thus binding the doubled back ends of the flexible metallic member in doubled back position between the two adjacent rows of blocks.
